Arum went on to promote 27 fights headlined by Ali, 20 with Marvin Hagler, 14 with George Foreman, 10 with Alexis Arguello, seven with Sugar Ray Leonard and all of Oscar De La Hoya's bouts through 2004. In 1980 he launched the Top Rank Boxing series on ESPN, which became one of the highest-rated regular shows during its run. He has also promoted major boxing events on HBO, SHOWTIME, ABC, NBC, CBS, Fox and Telefutura. Top Rank's current roster of talent includes Manny Pacquiao and champions Julio Cesar Chavez Jr., Nonito Donaire and Kelly Pavlik.
